Description

The B and BS bends are fittings designed to change the direction of airflow within air distribution systems while maintaining high aerodynamic performance and low pressure losses.

The pressed bends (B) are manufactured by stamping and are particularly suitable for small to medium diameters, ensuring high dimensional accuracy and quick installation.

The segmented bends (BS) are constructed by assembling multiple sections and represent the ideal solution for medium to large diameters, providing structural strength and smooth airflow continuity.

Both versions are widely used in ventilation, air conditioning, air handling, and air distribution systems for residential, commercial, and industrial applications.
